<H2 align="center">USE CASE 3: Designing configuration file format and cases </H2>
<p><B>Primary Actor: </B>Configuration Designer</p> 


<P><B>Stakeholders and Interests:<br>
</B>- Configuration designer wants to design a format and decides a list of denotations
for parameters for TraffoSim to parse to get a set of TraffoPackets and set other
environmental parameters. <br>
- Configuration designer wants to design a list of
cases with different parameter settings to fulfill defferent purposes. </P>
<P><B>Preconditions:</B>
  <br>
  - The developers of TraffoSim have decided what they need from the   configuration
  file, that is, the required data for generating TraffoPacket.  </P>

<P>
<B>Postconditions:</B>
<br>
- The format and the list of denotations for parameters of the configuration
file that satisfy the developers' needs are established. <br>
- A list of cases of
different parameter settings are designed. </P>

<B>Main Success Scenario:</B>
<OL>
<LI> Configuration designer gets a list of parameters to be put in the configuration
  file. 
<LI> Configuration designer decides how to represent the parameters and
  their legal values. 
<LI>Configuration designer designs a list of cases with
  different parameter values. (See <a href="sample_case.html">sample case design
  table</a>) 
<LI> Configuration designer sets up a format for
  TraffoPackets. (See <a href="config_format.html">XML format description</a>).
</OL>

<p><B>Alternative Scenarios:</B></p>

<P><B>GUI Interaction:</B><BR>
</P>
<P>
<B>Open Issues:</B><BR>
- Should the developer provide his/her preferred format?<br> 
- Should the developer
provides his/her preferred cases for parameter settings? </P>
